SPECIFICATION forming part of Letters Patent No. 324,788, dated August18, 1885.

Application tiled March 17, 1885. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL ROOKAFEL- LOW, a citizen of the United Statesof America, residing at Muscatine, in the county of Muscatine and Stateof Iowa, have invented certain new and useful Improvements inSulky-Plows, of which the following is a specification, refcrence beinghad therein to the accompanying drawings.

to My invention relates to sulky-plows; and it consists of devices forleveling the plow, and of devices for regulating the depth of the out ofthe plow, and for adapting it to be drawn by two horses or by threehorses, and for operating the plow by a person when riding on the sulkyor when walking behind the plow, all as hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a perspective view of myimproved plow. Fig.

2 is a side view with the plow and furrowwhecl removed. Fig. 3 is afront View of the tongue and the clevis attachments. Fig. 4 isaperspective view of the tongue-iron detached. Fig. 5 isa side view ofthe tongue attached to the equalizing-bar. Fig. 6 represents views ofthe guide and slide-platesdetached. Fig. 7 represents a section throughthe axle, showing the handle attachment.

A is the large sulky-wheel, A is the furrow- 0 wheel, and A is thesulky-axle. B is the plow-beam, B is the plow, and B is the drivers seatmounted on the spring-bar B. O is a handle attached to thesulky-axle bymeans of the flanged plate a, upon the upper portion 5 of which isformed a collar, a, to fit over the axle, and is provided with aset-screw, a for adjusting and holding the handle in any requiredposition.

The furrow-wheel A is journaled on a spin- 0 dle, a bolted on the arm 0,the forward portion of which is provided with the yoke-lugs a, and iscurved to fit the rear port-ion of the plow-beam, and is firmly attachedto the beam by means of the yokes a The wheel-arm G 5 is provided withthe axle-bearing b, which may be formed on or made separate and boltedto the arm. This bearing is provided with a set-screw, Z1, and is forthe purpose of and is adapted for carrying and holding one end of thesulky-axle in position. The other end of the sulky-axle is held in ahuh, I), provided with a set-screw, I)", which hub is formed on orattached to a plate, 0 The vertical edges of this plate are providedwith flange-guides to receive the slide-plate C the outside of which isprovided with a wheel-spindle, If, bolted to the plate, upon whichspindle is journaled the large sulky-wheel. To the upper middle portionof the slide-plate is pivoted a bar, If, to the upper end of which baris pivoted the end of a bell-crank lever here ina'fter described. On theupper portion of the plate G are formed the arms b If.

0* is a hand-lever, the lower portion of which forms a bellcrank, c, andis pivoted at the elbow to the arm I), and the end of the cranklever ispivoted to the bar b 0 is a notched sector, the lower end of which ispivoted to the arm If, and this sector extends through a guide on thelever O", the upper portion of which is provided with a spring-pawl, 0,adapted to catch in the notches in the sector 0 The wheel-arm G isextended backward, forming the sera-penarni O, to which is attached thescraper c by a boltinserted through a slot, 0 formed in the scraper totake up the wear upon the scraper and to enable it to be adjusted in therequired position to the furrowavheel.

C is a foot-board provided with the footrod, which foot-board isattached and supported in any suitable manner in position for thedrivers feet to rest on it.

D designates the rear portion of the tongue; 8 5 to which is bolted aplate, 0*, the forward end of which is provided with a slot, 0, throughwhich the forward bolt is inserted to allow oscillatory movement of thetongue. To the under side of the tongue-plate c is bolted the go plateD, bent downward, forming the bearing portion (1 and the projectingflange (1.

D is an equalizing-bar provided with the lugs (1 and with a series ofbolt-holes to re- I ceive the bolt extended through the bearing 5 d,which bolt fastens the tongue-iron D to the bar D This bar andthetonguc-iron D, at-

tached as described, are hinged to the clevis D of the plow by means ofa bolt, d, inserted through holes in the clevis and the bar-lugs 10o Itis evident that the equalizing-bar may be hinged to lugs or platesattached to the plow-beam instead of the clevis.

D is a flanged plate bolted to the bar D The back end of this plate isprovided with a series of holes for the purpose hereinafter named. i

D is a bar, the forward portion of which is bolted to the plate D, andthe rear end is provided with a stop-pin, d.

E is a hand-lever, on the lower portion of which is formed thebell-crank lever d This lever is pivoted at the elbow to a lug, f,formed on the forward end of the wheel-arm O, and the end of the leveris pivoted to a slide, f, on the bar D F is a notched sector, one end ofwhich is bolted to the plow-beam. This sector is extended through aguide attached to the side of the lever E, which lever is provided withaspring-pawl, h, adapted to catch and hold in the notchesof the sector.

The operation of the plow is as follows: The plow is adjusted in avertical position by means of the hand-lever O and its connectingdevices. When the plow is cutting a furrow and the wheel A is running inthe furrow,the lever is drawn backwardin positions indicated by dottedlines in Fig. 2 of the drawings, which lowers the other end of thesulky-axle and places it in a level position. And it is evident that bythe forward or backward movement of the lever, as required by the lay ofthe surface of the ground, the plow may be readily adjusted in avertical position, and it is held in that position by means of thespringpawl c in the notches of the sector 0 The handle 0 is providedwith a sub-handle, h, on the side. This handle and hand-piece are usedfor operating the plow by the operator when walking, and when the tongueis removed, the handle being adjustable to any required height by meansof the collar and set-screw. The flange-plate to which the handle isbolted affords additional strength to sustain the heavy pressurerequired in operating the plow. The sub-handle h is used in pulling theplow backward. The plow is adjusted to the required depth or height bythe forward and backward movement of the lever E and its connectingdevices. The point of the plow is raised by the backward movement of thelever and is lowered by the forward movement of the lever.

To raise the plow entirely out of the ground for turning and fortransporting the plow,the lever is drawn backward to nearly a horizontalposition, as shown by dotted lines in Fig. 2 of the drawings.

The series of holes in the plate D are for adjusting the plow for deepor shallow plowing. For deep plowing the bolt which connects the platewith the bar D is placed in the upper hole of the plate D, and forshallow plowing the bolt is placed in the lower hole. For medium depthof plowing the bolt is placed in the middle hole.

The plow may be readily adjusted to be drawn by two horses or by threehorses, and it is readily convertible from the one to the other bylocating the tongue on the bar, as required.

What I claim as new, and desireZto secure by Letters Patent, is

1. The combination,with the sulky-axle A, of the furrow-wheel arm 0,secured rigidly to the plow-beam, and the axle-bearing 12, formed on orattached to the arm, substantially as and for the purposes described.

2. The combinationfwith the sulky-plow axle, of the adjustable collar a,having the set-screw a the flange-plate a, and the handle 0,substantially as and for the purposes described.

3. The combination, w th the plow-beam B, of the equalizing-bar D,hinged to the beam, the slotted plate 0, and the tongue-iron D, boltedto the bar and to the tongue, substantially as and for the purposesdescribed.

4. The combination, with a plow-beam, B, and the equalizing-bar D,hingedto the beam, of the plate D, having a series of holes, the bar D theslide f, and the crank-lever E d, substantially as and for the purposesdescribed.

5. In a sulky-plow, the furrow-wheel arm 0, rigidly attached to theplow-beam, and with the wheel-spindle aiand having the portion 0extended backward beyond the spindle, in combination with the scraper 0attached to the extended arm, substantially as and for the purposesdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
